Should You Repair or Replace Your Furnace?

Repairing your furnace will usually be the cost friendlier option, but if your furnace is old, you should consider furnace replacement services. A new furnace will will require less maintenance costs and save you money in the long run. Typically, a furnace should last anywhere between ten to twenty years, so if your furnace is within this range, we suggest you consider having a new furnace installed.

4 reasons you may need our O'Fallon heater replacement services:

  • Lower your heating bill - Older furnaces tend to lose their efficiency over time. Naturally, when your furnace uses less fuel to keep your home warm, the less your bill will cost.
  • Avoid frequent repairs - Older furnaces may require maintenance often. If your furnace is in need of constant repair, you may need to look at getting a new model in order to provide peace of mind.
  • Increased comfort - An older furnace will get to a point where it is constantly having to run in order to keep your home warm for any length of time. A new furnace will make your home more comfortable with less effort and less fuel.
  • Helps keep you safe - With an older furnace, they are often more prone to leaking. This can result in a a carbon monoxide buildup. Making sure your furnace is replaced is by far the best option to keep you and your family safe.
